SSG-12Pro Solid Insulated Ring Network Switchgear
The SSG-12Pro solid insulation ring main unit will not have the risk of insulation failure like the SF6 switch, where the air pressure gradually decreases at low temperature.。
The greenhouse effect gas SF6 is canceled, and all materials are non-toxic and harmless environmental protection materials.。
· SSG-12Pro adopts a three-phase split design, and its external dimensions meet the requirements of the national grid standard, and the outer surface of the insulator adopts a metallization coating process.
· SSG-12Pro is a new future-oriented switchgear with features such as self-diagnosis, maintenance-free, low temperature resistance, miniaturization, flexible splicing, and environmental protection.
· All conductive parts inside the switch are sealed in solid insulating material.
· The main switch adopts vacuum arc extinguishing, and the isolating switch adopts a three-station structure.
· The adjacent cabinets are connected by solid insulated busbars.
· The secondary circuit adopts integrated control technology and supports data transmission function.
Parallel cabinet mode
Fully insulated, fully enclosed top expansion busbar system is used for easy installation.
Cable Warehouse
· Open the cable compartment only if the feeder is isolated or grounded
· Bushings according to DIN EN 50181, M16 screw connection.
· Lightning arrester can be attached to the back of the T-cable head。
· The one-piece CT is located on the side of the casing, making it easy to install cables and is not affected by external forces.
· The height from the casing installation place to the ground is greater than 650mm.
Pressure relief channel
If an internal arc fault occurs, the special pressure relief device installed in the lower part of the body will automatically start to relieve pressure.
Fully sealed operating mechanism
The circuit breaker adopts a precision transmission mechanism with reclosing function, and the output track of the isolation mechanism is sinusoidal to ensure that the closing and opening positions are accurate. The mechanism room and the main circuit adopt a fully sealed design, and the secondary control circuit connection adopts a sealed plug structure. The switch can be immersed in water for more than 96 hours, completely avoiding mechanism corrosion caused by external water vapor or pollution, failures such as refusal to open and close, and malfunction of the control circuit, resulting in skipping trips and eventually causing large-scale power outages.
Isolation switch
The isolating switch adopts the direct acting type and is equipped with a spring finger contact structure, which has small contact resistance, low temperature rise and large carrying capacity, ensuring that any switch can meet the short-term withstand current of 25kA /4 seconds.
Insulation and sealing design
The phases adopt an independent compartment structure to avoid explosion accidents caused by short circuits between phases. The primary conductor adopts a circular or spherical structure and is equipped with high-voltage shielding outside. The surface of the insulator is coated with metal and grounded reliably to ensure uniform distribution of high-voltage electric fields and ensure that external pollution will not have any impact on the insulation system.
The customer only needs to package the core unit modules in the cabinet.
We provide customers with a full range of cabinet drawings, secondary schematic drawings, product manuals, promotional materials, technical consultation and other services free of charge.
The core unit module can be sold separately to the public, and all parameters have been adjusted in place before leaving the factory, so customers do not need to debug again.
